Q
What is a Cisco X2 module?
A
A Cisco X2 module is a hot-swappable 10 Gigabit Ethernet optical transceiver designed for Cisco switches and routers in a compact form factor.
Q
What data rate do Cisco X2 modules support?
A
Cisco X2 modules support a data rate of 10.3125 Gbps for 10 Gigabit Ethernet applications.
Q
Which fiber types are compatible with Cisco X2 modules?
A
Cisco X2 modules are compatible with multimode fiber (MMF) and single-mode fiber (SMF) depending on the transceiver model.
Q
What is the maximum transmission distance for Cisco X2 modules?
A
Depending on the model, Cisco X2 modules can transmit up to 300 m on multimode fiber and up to 80 km on single-mode fiber.
Q
How do I install a Cisco X2 module in a Cisco switch or router?
A
To install a Cisco X2 module, power down the device if required, align the module with the port, insert until the latch clicks, then reconnect power and verify link status.
Q
Are Cisco X2 modules hot-swappable?
A
Yes. Cisco X2 modules support hot-swappable installation and removal without powering down the host device.
Q
What optical connector type do Cisco X2 modules use?
A
Cisco X2 modules use a duplex LC optical connector to ensure secure and low-loss fiber alignment.
Q
How do I choose the right Cisco X2 module for my network?
A
Select a Cisco X2 module by matching required data rate (10 Gbps), fiber type (MMF or SMF), transmission distance, wavelength, and compatibility with your Cisco platform.
Q
Can Cisco X2 modules support 10 Gigabit Ethernet?
A
Yes. Cisco X2 modules are specifically engineered to support 10 Gigabit Ethernet links in enterprise and data center networks.
Q
How does Cisco X2 compare to Cisco XENPAK and XFP modules?
A
Compared to XENPAK, Cisco X2 modules are 40% smaller and consume less power; vs. XFP, X2 offers integrated digital diagnostics and direct host interface support.
Q
Do Cisco X2 modules support Digital Optical Monitoring (DOM)?
A
Yes. Cisco X2 modules feature DOM for real-time monitoring of optical output power, input power, temperature, voltage, and laser bias current.
Q
What wavelengths are available in Cisco X2 modules?
A
Cisco X2 modules are available in 850 nm for short reach, 1310 nm for medium reach, and 1550 nm for long-reach single-mode applications.
Q
Are third-party Cisco X2-compatible modules reliable?
A
Quality third-party Cisco X2-compatible modules can meet or exceed OEM specifications when sourced from reputable vendors who test for interoperability.
Q
How do I troubleshoot a Cisco X2 module link failure?
A
Verify fiber polarity, inspect connectors, check module compatibility, and use the Cisco IOS command ‘show interfaces transceiver details’ to identify errors.
Q
How do I verify that a Cisco X2 module is recognized by my device?
A
Use the Cisco IOS command ‘show interface transceiver’ or ‘show module’ to confirm that the X2 module is detected and operating correctly.
Q
What factors affect the price of Cisco X2 modules?
A
Pricing depends on brand (Cisco vs. third-party), module type (MMF or SMF), maximum reach, wavelength, and support for enhanced diagnostics.
